Hi Stuart:
My host /etc/exports file is:
/tftpboot/ltib 192.168.1.100(rw,no_root_squash,sync)
/tftpboot/ltib is a link to the root file system
/tftpboot/ltib -> /home/vrams/mpc8536ds/ltib/rootfs
I also changed /home/vrams/mpc8536ds/ltib/rootfs/etc/exports file to:
/tftpboot/ltib 192.168.1.100(rw,no_root_squash,sync)
But that didn't help

Here's another clue:
When I don't explicitly define console& null in my rootfs/dev, it gives
up immediately. Can't open console?

Hi Carolyn,
Make sure you have the right export permissions on your NFS server. For
example, make sure you have no_root_squash listed in the options.
You can verify this independently by mounting the rootfs on some other
machine and trying to touch a file somewhere on that filesystem.
Regards, Stuart

I am trying to boot my baseline uImage& dtb built (dated 22-Jul-2010)
using
LTIB dated 13-Mar-2009 for
Freescale MPC8536DS
Linux 2.6.28 for PPC
I have attached the log from the bootloader.
It won’t boot any more. Wondering if I messed up the file system
somehow.
During the boot process every mount fails after NFS filesystem mounted:
mount: permission denied. (are you root?)
All files are at the user level, not root.
Could I have copied the directory incorrectly?
How do I fix?
Thanks. This is my baseline and it doesn’t work!
